# ef.js

Unclassified · [Official website](https://ef.js.org)

ef.js is an open source JavaScript framework for building user interfaces from declarative templates with a lightweight, component-based approach. It updates the page through data binding without relying on a virtual DOM, and is designed to stay small. As a client-side library, it does not in itself set cookies or send visitor data to a third party.
